ABSTRACT:
Programmable transcoding device which sequences of binary words of variable lengths corresponding to strings of characters in a first alphabet are transcoded into other sequences of binary words intelligible in a second alphabet. The device is connected to digital systems exchanging sequences of words via interfaces provided with files. A CPU connected to the interfaces via a switching device receives the incoming sequences, and delivers transcoded outgoing sequences of binary words. An exchange management unit monitors the data transfers in the device and regulates the flows of words between the device and the digital systems. A terminal or microcomputer can also equip the device so as to produce transcoding tables to be downloaded in an RAM of the CPU.
